Not providing a cap on spending is a major flaw of GCP for individuals / small projects.

With Cloud Run, AFAIK, spending can effectively be capped by: limiting concurrency, plus limiting the max number of instances it can scale to. (But this is not as good as GCP having a proper cap.)

[brutus1213]

Amazon is the same I think? I live in constant fear we will have a runaway job one day. I get daily emails to myself (as a manager) and to my finance person. We had one instance where a team member forgot to turn off a machine for a few months :(

I get why it is a business strategy to not have limits .. but I wonder if providers would get more usage if people had more trusts on costs/predictability.

I remember going out to dinner, years ago, with a fairly senior AWS billing engineer. An acquaintance of a coworker.

He looked completely surprised when I asked about runaway billing and why there wasn't any simple options to cap a given resource to prevent those cases.

His response was that they didn't build that because none of their customers wanted anything like that, as far as he was aware.

Disclaimer: I work at Google but not on cloud. Opinions my own.

I think the reason this doesn’t get prioritized is that large customers don’t actually want a “stop serving if I pass this limit” amount. If there’s a spike in traffic, they probably would rather pay the money to serve it. The customers that would want this feature are small-dollar customers, and from an economic perspective it makes less sense to prioritize this feature, since they’re not spending very much relative to customers who wouldn’t want this feature.

Maybe if there weren’t more feature requests to get prioritized this might happen, but the reality is that there are always more feature requests than time to implement them, and a feature request used almost exclusively by the smallest dollar customers will always lose to a feature for big-dollar customers.

I guess where it could potentially bring value is by:

Removing a major concern that prevents individuals / small customers from using GCP in the first place; so more of them do use it

That could then lead to value in two ways:

- They make small projects that go on to be large projects later, (e.g. a small app that grows / becomes successful, becomes a moneymaker)

- Or, they might then be more inclined to get their big corp to use GCP later on, if they've already been using it as an individual

But that's long term, and hard to measure / put a number on

[jiggawatts]

Every large enterprise has insurmountable difficult even imagining why customers would want something as bizarre as a "stop loss" on their spending...

... right up until it's their own bottom line that is at risk, and then like magic spending limits become a critical feature.

For example, Azure has no stop-loss feature for paid customers, but it does for the "free" Visual Studio subscriber credits. Because if some random dev with a VS subscription blows through $100K of GPU time due to a missing spending constraint, that's Microsoft's problem, not their own.

It's as simple as that.

As noted above, there is enough value here such that AWS implemented this several years ago. Said implementation is appropriate for both personal AWS accounts and large scale multi-account organizations.

Having implemented this on behalf of others several times, I'll share the common pain points: * There's a long lead time. You need to enable Cost Explorer (24-48 hours). If you're trying for fine distinctions, activating tags as cost allocation tags is another 24 hours * AWS cost data is a lagging indicator, so you need to be able to absorb a day of charges * Automation support is poor, especially for organizations * Organization budgets configured at the account level are misleading if you don't understand how they're configured

What's really wanted here is that AWS needs to commit to more timely cost data delivery such that you can create an hourly budget with an associated action.

> Said implementation is appropriate for both personal AWS accounts and large scale multi-account organizations.

Followed by a list of caveats that make it wholly irrelevant for an individual who is afraid of a surprise charge covering less than several days.

[dragandj]

Yeah, right. Capping a resource, such a wild idea. Of course they won't implement it for the same reason bar owners don't put a cap on drinks.

[ElevenLathe]

Aren't bars actually required to cap drinks? It's usually phrased as having to refuse serving if you're visibly drunk, but still effectively a cap. That said, a big cloud bill doesn't make you intoxicated. The more I examine this analogy, the less it makes sense.

[mtrovo]

I don't know if the analogy works that well, the assumption is that you're making more money then you put in the more traffic you get. As a bar owner is the choice between closing your bar for the month when you run out of beer or running to the supplier to bring more kegs.

[sidibe]

I'm sure lot of people at Amazon and Google are aware small customers want this and it's a feature they'd like to brag about, but it is much harder to implement a real time quota on spend than a daily batched job for the money part + realtime resource scoped quotas.

[152132124]

None of their Big Customers they meant, the small ones who worry about this doesn't matter.

[coredog64]

There's a coarse option: Set up a budget and then a budget action. While ECS doesn't have GPU capabilities, the equivalent here would be "IAM action of budget sets deny on expensive service IAM action" (SCP is also available, but that requires an AWS Org, at which point you've probably got a team that already knows this)

It's coarse because it's daily and not hourly. However, you could also self-service do some of this with CloudWatch metrics to map to a cost and then have an alarm action.

What is the strategy? Is is purely market segmentation? (As in: "If you need to worry about spending too much, you're not the big-money kind of enterprise customer we want"?)

[nprateem]

It's not a strategy. It's technically difficult, opens them to liability if runaway happens so fast their system can't stop it, and is only wanted by bottom of the barrel customers.

[physix]

Just a thought: Maybe if they had some kind of opt-in insurance against overuse until the circuit breaker can kick in?

But, looking from the outside, the lack of protection is effectively a win for them. They don't need to invest in building that out, and their revenue is increased by not having it (if you ignore the effect of throttling adoption). So I have always assumed that there is simply no business case for that, so why bother?

[edit - Gabe responded]. See this Cloud Run spending cap recommendation [0] to disable billing, which potentially irreversibly deletes resources but does cap spend!

[badrequest]

Sure, but why post a tutorial of how to spin this up in GCP instead of...productizing it in GCP?

[gabe_monroy]

Heard on this feedback. While not quite a hard cap, I'd also point to https://cloud.google.com/billing/docs/how-to/budgets which many customers are having success with for this use case.

[advisedwang]

It's rock and a hard place for the cloud providers.

Cap billing, and you have created an outage waiting to happen, one that will be triggered if they ever have sudden success growth.

Don't cap billing, and you have created a bankruptcy waiting to happen.

[delfinom]

Flaw? Nah

Feature for Google's profits.
